Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to an anti-seepage and drainage structure for roadside ditches of roads. Background Technique

[0002] In road engineering, as the core component of the subgrade drainage system, the anti-seepage and drainage performance of roadside ditches directly affects the stability of the subgrade. The traditional roadside ditch structure is made of a single material such as concrete or grouted rubble masonry. In rainy areas, the subgrade is prone to softening due to seepage. Its material durability and structural anti-deformation ability are not ideal enough to meet the requirements of complex geological conditions and heavy traffic. Therefore, in order to meet the anti-seepage and drainage requirements of roadside ditches, we propose an anti-seepage and drainage structure for roadside ditches.

[0003] The following defects also exist in the prior art during use:

[0004] 1. The drainage speed of the anti-seepage and drainage structure of the roadside ditch in the prior art is not ideal enough. When the drainage volume is large, it is easy to cause the water inside the ditch to return to the road surface due to the slow drainage speed, resulting in water accumulation on the road surface and backwater in the sewer.

[0005] 2. The anti-seepage effect of the anti-seepage and drainage structure of the roadside ditch in the prior art on the subgrade is not ideal enough, and the structural strength of the traditional roadside ditch cannot meet the use on soft subgrade roads. The traditional roadside ditch is prone to deformation and fragmentation, thus greatly reducing the drainage, anti-seepage performance and support effect of the ditch.

[0006] In view of this, we propose an anti-seepage and drainage structure for roadside ditches to solve the existing problems. Content of the Utility Model

[0031] Embodiment 1, as shown in Figures 1-5As shown in the figure, a road gutter anti-seepage and drainage structure proposed by the present utility model includes a base 1, an inner groove 2, a filtering base 3 and an outer groove 4. A water guide groove 105 is provided inside the base 1, and both sides of the bottom of the water guide groove 105 are arc-shaped. A number of drainage holes 102 are provided on both sides of the base 1. The drainage holes 102 are arranged obliquely downward, and the drainage holes 102 are all communicated with the water guide groove 105. Reinforcing plates 103 are fixedly installed on both sides of the top of the base 1. The reinforcing plates 103 are wedge-shaped structures. The back sides of the two reinforcing plates 103 are inclined planes, and a number of anti-slip grooves are provided on the inclined planes. The base 1 can support the components on the top and expand the overall supporting area of the device for the bottom roadbed, thereby reducing the pressure exerted by the device on the roadbed. On the one hand, the overall stability of the device is improved, and on the other hand, it can prevent the overall device from settling inside the roadbed. The water guide groove 105 can guide water, so that the water entering the base 1 is discharged from the base 1 through the drainage holes 102 respectively. The drainage holes 102 can guide the water inside the water guide groove 105 to be quickly discharged, thereby improving the overall drainage efficiency of the device. The reinforcing plates 103 can provide lateral support for both sides of the outer groove 4 to improve the overall stability and structural strength of the outer groove 4 and its inner components;

[0032] An outer groove 4 is installed between the two reinforcing plates 103 at the top of the base 1, and the outer groove 4 is a U-shaped groove structure. A number of reinforcing beams 402 are installed on the lateral inner walls of the outer groove 4. The reinforcing beams 402 are made of granite material. A sealing brick 401 is fixedly installed at the top of the reinforcing beam 402, and waterproof glue is filled at the edge position of the sealing brick 401. The outer groove 4 can provide an installation position for the inner components, and the bottom of the outer groove 4 is a permeable structure, which can make the filtered water flow into the base 1. The reinforcing beams 402 can reinforce the inner groove 2, so that the adjacent two sections of the outer groove 4 and the inner groove 2 are pulled together, thereby achieving the purpose of improving the overall structural strength and reducing the probability of the gutter being broken and deformed. The sealing brick 401 can seal between the outer groove 4 and the inner groove 2, thereby preventing the water at the top from directly flowing into the outer groove 4 through the reinforcing beam 402;

[0033] A filtering base 3 is arranged at the bottom inside the outer groove 4. A coarse base 301 is laid on the top of the filtering base 3. The filtering base 3 can support the coarse base 301 and filter the sewage flowing out of the inner groove 2. The coarse base 301 can further improve the supporting effect at the bottom of the inner groove 2 and can preliminarily filter the sewage discharged from the inner groove 2;

[0034] At the top of the rough base 301, an inner groove 2 is fixedly installed. At a position near the bottom on the side of the inner groove 2, a plurality of drainage grooves 202 are provided. At the bottom inside the inner groove 2, a plurality of water guide bricks 201 are laid. At the top of the inner groove 2, a manhole cover 203 is snap-fitted and installed. The inner groove 2 can provide an installation position for the inner components, and guide the sewage to flow quickly inside the device and be discharged, so as to improve the sewage discharge efficiency of the device. The drainage grooves 202 can enable the sewage inside the inner groove 2 to be quickly distributed and discharged, thereby improving the sewage discharge efficiency of the inner groove 2. The water guide bricks 201 can guide the sewage entering the inner groove 2, making the sewage flow towards the drainage grooves 202 and be discharged from the drainage grooves 202 out of the inner groove 2. The manhole cover 203 can cover the top of the inner groove 2, thereby preventing large-volume sundries from falling into the inner groove 2. The round holes inside the manhole cover 203 can enable the sewage to flow through the manhole cover 203 and into the inner groove 2.

[0035] Furthermore, on both sides of the top of the base 1, side blocks 101 are provided, and the side blocks 101 are in contact with one side of the reinforcement plate 103. The side blocks 101 can enhance the lateral structural strength of the reinforcement plate 103, thereby preventing the reinforcement plate 103 itself from shifting and affecting the limiting effect of the reinforcement plate 103 on the outer groove 4.

[0036] Furthermore, a plurality of support plates 104 are fixedly installed at equal intervals inside the water guide groove 105, and the support plates 104 are in an inverted V-shaped plate structure. The support plates 104 can enhance the longitudinal support strength of the base 1 and prevent the base 1 from collapsing.

[0037] Furthermore, the base 1 is made of concrete material, and a plurality of water drainage holes 106 are opened at the top of the base 1. The water drainage holes 106 are arranged in an inclined direction, and two adjacent water drainage holes 106 are communicated. The water drainage holes 106 can enable the sewage inside the base 1 to be quickly discharged, so as to cooperate with the inner groove 2 and the outer groove 4 to quickly discharge the sewage into the roadbed, and prevent a large amount of sewage from forming ponding on the road surface.

[0038] Furthermore, the inner groove 2 adopts a U-shaped groove structure, and the inner groove 2 is made of reinforced concrete material. The inner groove 2 can provide an installation position for the surrounding components and guide the sewage on the road surface to quickly drain into the roadbed.

[0039] Furthermore, the water guide bricks 201 are in contact and connected with each other, and the water guide bricks 201 are in a wedge-shaped structure. A plurality of water guide bricks 201 are spliced to form a wave-like structure, and the position of the lower part of the water guide bricks 201 coincides with the position of the drainage grooves 202. The wave-like structure formed by the water guide bricks 201 can enable the sewage inside the inner groove 2 to be discharged in segments, thereby avoiding the problem of low drainage efficiency in the traditional side ditch centralized drainage, and being beneficial to reducing the probability of ponding on the road surface.

[0040] Further, a round hole is provided at the central position of the manhole cover 203, and anti-slip patterns are provided on both sides of the top of the manhole cover 203.

[0041] Further, the inside of the reinforcing beam 402 is filled with a composite material, and the composite material is made by mixing polyurethane, extruded polystyrene and foam glass. The volume ratio of polyurethane is 15% to 25%, the volume ratio of extruded polystyrene is 35% to 45%, and the volume ratio of foam glass is 35% to 45%. The reinforcing beam 402 can enhance the structural strength of the position between the inner groove 2 and the outer groove 4. In cooperation with the composite material filled inside the reinforcing beam 402, a tension structure is further formed between the inner groove 2 and the outer groove 4. And after the reinforcing beam 402 is filled with the composite material, it integrates the functions of reinforcement and heat preservation. On the one hand, it can enhance the overall structural strength of the inner groove 2 and the outer groove 4, on the other hand, it can prevent the water inside the device from being affected by the roadbed temperature when flowing, and can also prevent the internal structure of the device from being damaged when the temperature changes suddenly.

[0042] Further, grooves are provided on both sides of the top of the coarse base 301, and a plurality of filter tiles 302 are installed on the top of the grooves. A water guide plate 303 is installed on the top of the filter tiles 302, and a plurality of round holes are provided inside the water guide plate 303. The top of the water guide plate 303 is fixedly connected to the bottom of the reinforcing beam 402. The coarse base 301 can support the inner groove 2 and preliminarily filter the sewage quickly discharged from the inner groove 2.

[0043] Further, the filter base 3 is made by mixing gravel, quartz sand and geotextile, and the mixing weight ratio of gravel and quartz sand is 3:2. The laying layer number of the geotextile is at least 3 layers. The coarse base 301 is made by mixing cobblestones and zeolite, and the mixing weight ratio of cobblestones and zeolite is 3:2. The filter base 3 can further filter the sewage flowing out of the coarse base 301, so as to prevent a large amount of impurities from flowing into the base 1 and causing blockage of the base 1.

[0044] Working principle: After the trench is dug in the roadbed, the base 1 is hoisted and placed at the bottom of the side ditch. After the reinforcing plates 103 are respectively installed on both sides of the top of the base 1, the outer groove 4 is fixedly installed between the two groups of reinforcing plates 103. The filter base 3 is filled in the outer groove 4. After the filling of the filter base 3 is completed, there is no need to compact. Then, the coarse base 301 is continuously filled on the top of the filter base 3. After the filling of the coarse base 301 is completed, the remaining components and the inner groove 2 are installed, and the manhole cover 203 is covered to complete the assembly;

[0045] When there is a large amount of sewage on the road surface on a rainy day, the sewage flows into the inner tank 2 through the manhole cover 203. The water guide bricks 201 guide the sewage entering the inner tank 2, so that the sewage is discharged from the drainage tank 202 in sections. After the sewage is discharged from the inner tank 2, it first contacts the coarse base 301. After primary filtration through the coarse base 301, it is then secondarily filtered through the filter base 3. The filtered sewage flows into the water guide groove 105 through a number of sewer holes 106, and then flows into the roadbed from the base 1 through the drain holes 102, thus completing rapid drainage;

[0046] When there is a large amount of moisture inside the roadbed, the moisture at a lower position enters the water guide groove 105 through the drain holes 102 and accumulates. As the moisture in the water guide groove 105 continues to increase, the internal pressure increases, inhibiting the continuous entry of moisture into the base 1, forming an anti-seepage effect. The roadbed at a higher position directly contacts the reinforcement plate 103, and a partition is formed through the reinforcement plate 103 and the outer tank 4 to prevent the moisture in the roadbed from seeping in, thereby achieving an anti-seepage effect.

[0047] Embodiment 2 is different from the above embodiment in that in this embodiment, the filter base 3 is composed of a mixture of pebbles, volcanic rock particles and zeolite particles. The volume ratio of pebbles is 40% to 50%, the volume ratio of volcanic rock particles is 30% to 40%, and the volume ratio of zeolite particles is 20% to 30%. The main function of the pebbles is to support and perform simple filtration. The volcanic rock particles utilize their own adsorption properties to achieve adsorption filtration of impurities in the sewage, removing suspended solids and heavy metal substances in the sewage, and preventing heavy metal substances from entering the roadbed with the sewage and causing heavy metal pollution to the soil environment. The zeolite particles adsorb pollutants such as ammonia nitrogen and heavy metals through ion exchange, and do not affect the overall water permeability of the filter base 3. After the sewage enters the filter base 3, not only can a good filtration effect be obtained, but also the overall drainage efficiency of the device will not be affected.

[0048] The above specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
